How do I engage the night vision system in my Audi A8 at night?

I have an Audi A8 with a night vision system, but I'm not sure how to use it during nighttime driving. Can someone please walk me through the steps to engage it?

To engage the night vision system in your Audi A8 at night, simply press the night vision button located on the control panel. This will activate the infrared camera and allow you to see up to 300 feet ahead of your vehicle in low light conditions. When not in use, the night vision system will automatically switch off to avoid draining the battery.
